SHUTTLE-LOCKING MEANS FOR LOOIVIS.

SPECIFICATION forming part of Letters Patent N0. 787,832, dated April18, 1905.

Application filed November 18. 1904. Serial No. 233,319.

To (1J7 whom, it nm concern:

Beit known that l, H ENnY COTE, a citizen of the United States, and aresident of \Vest \Varren, county of "orcestQr, State of Massachusetts,have invented an Improvement in Shuttle-Locking Means for Loomsof whichthe following description, in connection with theaccompanying drawings,is a specification, like characters on the drawings representing likeparts.

This invention has for its object the production of novel means forautomatically locking the shuttle in the shuttle-box of a loom toprevent rebound of the shuttle upon striking the picker and to moreaccurately position the shuttle for subsequent operations. If theshuttle rebounds, it is not started from the box at the next pick andmay fail to reach the opposite box or to box properly, the pickingbecoming irregular and producing a bad effect on the cloth. If the loomis provided with automatic lilling-replen ishing mechanism, it is highlyimportant for the proper operation of such mechanism that the shuttleshall be accurately positioned in the box, a condition which manifestlycannot be fulfilled if the shuttle rebounds.

The various novel features of my invention will be fully described inthe subjoined specilication and particularly pointed out in thefollowing claims.

Figure 1 is a top or plan view of a portion of a loom, showing ashuttle-box equipped with one embodiment of my invention and with theshuttle locked in the box. Fig. 2 is a detail in front elevation of aportion of the shuttle box, the front wall thereof being broken out toshow the shuttle-locking means. Fig. 3 is a rear view of the lockingmeans and the shuttle just before it is engaged thereby; and Fig. l is aplan view, partly broken out, of the outer end of the shuttle-box,showing the outgoing shuttle just as it has been released by the lockingmeans.

The lay 1, longitudinally slotted at 2 for the reception of thepickerstick 3, having an attached pickerlr, the shuttle-box, comprisinga front plate 5 and top or cover plate (5, and

shuttle S may be and are all of well-known construction.

In Fig. l l have shown a portion of the filling feeder or hopper F andtransfcrrer f" of automatic filling-replenishingmechanism substantiallyof the type shown and described in United States Patent No. 529,940 toautomatically insert a fresh filling-carrier into the running-shuttle,the latter being shown of the automatically self threading type. If theshuttle rebounds, it will not only fail to be picked properly, but in anautomatic fillingreplenishing loom the incoming filling-carrier will notbe inserted properly in the shuttle, and a breakage of the shuttle orsome of the adjacent parts of the mechanism willbe almost certain tooccur.

In accordance with my present invention I attach to the picker aneh'mgated spring finger or catch 9, extended toward the center of theloom and having at its extremity a lug or projection 10. Herein thecatch is shown attached to the rear side of the picker by suitablescrews 11, Fig. 3, and the projection l0 is on the front face of thecatch, the latter being bent rearward, (see Fig. 4-.,) so that theshuttle-point can pass the projection and impinge against the face ofthe picker. The length of the catch is such that when the shuttleengages the pickcr the projection 10 will be directly opposite a recessa in the side of the shuttle, and in the present instance this reccss isthe socket which receives the end of the screw which holds thethrezuling-block in place. An upright elongated lug 12 is fixedlymounted on the lay just behind the shuttle-path and parallel theretoback of the spring-catch 9 and at such a point that the outward movementof the shuttle after impinging upon the picker will cause the catch towipe over the lug and the latter will press the projection 10 into therecess x in the shuttle. This is shown in Fig. 1, the shuttle beingpositively connected with the picker, and thereby held from reboundingand at a definite position in the shuttle-box. \Vhen the picker is movedinward to throw the shuttle from the box, the catch maintains theconnection between picker and shuttle until the catch is free to springoutward, having passed beyond the control of the lug 12, as shown inFig. 4:. Just at the instant the springcatch is thus i'reed it withdrawsthe projection 10 from the recess in the shuttle and the latter is freeto travel across the lay. The binder B is bent rearward at b to clearthe lug 12, and a longitudinal recess 6 is made in the binder-face (seeFig. 4) to permit the catch 9 to operate, as has been described.

From the foregoing description it will be manifest that the shuttle islocked in the box by means controlled by the picker and that the shuttleis released from such locking means by or through the inward stroke ofthe picker. The lug l2 constitutes a controlling device to press thelocking projection into cooperation with the shuttle and to retain theparts in cooperation until the picker and shuttle have moved inward to apredetermined point.

My invention is not restricted to the precise construction andarrangement herein shown and described, as the same may be varied ormodified in different particulars by those skilled in the art withoutdeparting from the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a loom, a lay havinga shuttle-box, a picker, and means movabletherewith to automatically lock the shuttle in the box and preventrebound.

2. In a loom, a lay having a shuttle-box, a picker, means movabletherewith to automatically lock the shuttle in the box as it moves tothe end of its stroke with the picker, and means to release the shuttleby or through the inward stroke of the picker.

3. A loom having in combination a lay provided with a shuttle-box, apicker, a locking member carried thereby, and means to effect positiveengagement of the said member and the shuttle as the latter reaches theend of its stroke.

4:. A loom having in combination a lay provided with a shuttle-box, apicker, means to temporarily and positively connect the picker and theincoming shuttle to prevent its rebound, and a controlling device forsaid means.

5. A loom havingin combination a lay provided with a shuttle-box, apicker, a springcatch mounted thereon, a shuttle having a recess to beengaged by the catch, to eifect the connection of the shuttle with thepicker, and a controller fixedly mounted on the lay, to press the catchinto engagement with the shuttle as the latter reaches the end of itsstroke, the catch releasing the shuttle when the inward stroke of thepicker has carried the catch beyond the range of the controller.

6. In a loom, in combination, mechanism to automatically insert a freshsupply of filling in the shuttle, a picker, and automatic means movabletherewith to automatically lock the shuttle in position to receive afresh supply of filling, said means releasing the shuttle by or throughthe inward stroke of the picker.

7. In a loom, in combination, mechanism to automatically insert a freshsupply of filling in the shuttle. a picker, a yielding catch mountedthereon and having a projection at its inner end, a shuttle having arecess adapted to receive said projection when the shuttle is to belocked, and means on the lay to force the projection into the recesswhen the shuttle has reached a predetermined point in its movement, tothereby retain the shuttle in position for filling replenishment.

8. In a loom, a lay provided with ashuttlebox, a binder, a picker, andmeans movable therewith and operating independently of the binder tolock the shuttle from rebound and to automatically release it by orthrough the inward stroke of the picker.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. A

HENRY COTE.
